The packet will be transmitted repeatedly until an acknowledgement is received or
until the packet has been sent RR times.
Note: For retries to work correctly, all modules in the system must have
retries enabled.
RS (RSSI) Command
<Diagnostics> Read the signal
level of the last packet
received. This reading is useful
for determining range
characteristics of the modules
under various conditions of
noise and distance.
Once the command is issued, the module will return a value between 0x06 and 0x36.
(„0x36‟ represents a very strong signal level and „0x06‟ indicates a low signal level.)
RT (DI2 Configuration)
Command
<Serial Interfacing> RT
command is used to dictate
the behavior of the
DI2/RTS/CMD line. RT
Command must be issued to
enable RTS flow control or
binary programming.
RZ (DI Buffer Size)
Command
<Diagnostics> The RZ
command is used to read the
size of the DI buffer (UART
RX (Receive)).
Note: The DO buffer size can
be determined by multiplying the DI buffer size by 1.5.
